2. Description of the Related Art Conventionally, as a method of installing a flat display device, for example, a liquid crystal display or a plasma display, there are wall-mounting, ceiling-mounting, floor-mounting, or desk-mounting, depending on the application and screen size. The installation method was appropriately selected and installed. FIG. 10 shows a conventional installation method for floor installation or desk installation. FIG.
(A) is an example of an installation device 101 of a flat display device when installed immediately before a wall surface, and is installed from an installation stand portion 102 arranged on a floor surface and a rear portion of the installation stand portion 102. And a display mounting portion 105 which is disposed on the upper end of the support column 103 and mounts the support column 103 and the flat display device 104. By the way, in the case of this example, since the entire installation device 101 is close to the wall surface or the like on the back surface, the space factor is good, and the device does not fall backward. However, since the flat display device 104 is thin, the center of gravity is located at the rear, and when the installation device 101 is made to stand alone by itself, there is a risk of falling backward.

[0003] Therefore, in preparation for the case where the installation apparatus 101 is made to stand alone by itself, as shown in FIG. However, in such an example, even in the case where the rear surface is a wall surface, it is equivalent to the entire installation device 101 having moved forward. There is a problem that the space factor of the surface is deteriorated and becomes an obstacle. This problem is set up on a desk.
The same applies to an example as shown in (c). In the case of such a desk-mounted installation apparatus 101a, the installation place of the desk 106 is not particularly limited. Installation stand part 10 for prevention
It is necessary to shift the column 103a forward with respect to 2a.
For this reason, there is a problem that the front becomes narrow because a useless space is needed behind, and the desk cannot be used effectively.

The protruding means locks the auxiliary stand section by engaging with a rod-shaped member that moves downward when the installation stand section is separated from the floor or a desk, and a tip end of a rod-shaped member 95 provided in front of the auxiliary stand section 93. A hook 93a is held at a predetermined position, and a spring member 94 biases the auxiliary stand 93 backward. With the above configuration, as shown in FIGS. 9A and 9B, the auxiliary stand 93 normally has the hook 93 a engaged with the rod-shaped member 95 and is stored in the installation stand 92. Has become. When the front portion of the installation stand portion 92 floats due to an earthquake or the like, the rod-shaped member 95 moves downward by the elastic force of the spring member 96,
The hook 93a is released. When the lock of the hook 93a is released, the auxiliary stand 93 protrudes rearward by the pressing force of the spring member 94. Thereby, even if the installation device is slightly inclined due to an earthquake or the like, it is possible to prevent the installation device from falling.
Further, since the locking means 92b for locking the operation of the projecting means is provided during transportation or when the projecting means is not necessary, careless projection of the auxiliary stand 93 is prevented. The locking means 92b is composed of a rotatable hook, a stopper, and the like. Although the figure shows a case where the spring member 94 is normally retracted and extended at the time of projection, it may be normally extended and retracted at the time of projection.
